Owner Maintenance
WARNING
Do not replace the main fuse by
yourself. Have an expert repairer
(we recommend an Authorised
Mazda Repairer) perform the
replacement:
Replacing the fuse by yourself is
dangerous because the MAIN fuse
is a high current fuse. Incorrect
replacement could cause an
electrical shock or a short circuit
resulting in a fire.
4. Reinstall the cover and make sure
that it is securely installed.
